I was referred by GenSun Roofing by my neighbor and I’m so thankful for it! The presentation was second to none…Jim was amazing to work with and answered all my questions/concerns. The crew was equally skilled and meticulous. Highly recommend!
Thanks to both you and Matt.
Awesome job!!! The team came out and made sure the job was done in a timely manner.
Thank you for your kind comments.
I had such a wonderful stress free experience right from the beginning. They easily gave me an estimate without having to sit with a high pressure sales person. They even provided me videos so I could learn about what they do and they showed me what roof would like before I hired them. Thank you so much and highly recommended. Shirley Rohloff
We had the roof on our house completely replaced by Celso and his crew of 6x workers from GenSun Roofing. As we progressed during the day we had some minor issues but once the crew chief Celso was notified they were corrected within a short time and work continued. The Team worked very hard and long hours to have our job completed on time and ahead of schedule for a great price. They even went the extra mile to correct an issue with our existing fascia. I would highly recommend GenSun Roofing to friends and family for they did a great job and our new roof looks awesome.
Thank you very much for acknowledging our Crews efforts to satisfy you.
Great company and even better people! Overall experience was an enjoyable process and my new roof / gutters look great! Next up I’m thinking about solar panels!
Of course we are, you are one of us! lol We love taking care of our co workers.
Life savers, I had a some big tree branches that fell on top of my kitchen's roof. I started calling around and some places won't even answered the phone. one of my co-workers gave me a referral for GenSun Roofing and I decided to get in contact with them. from day showed empathy and se up and appointment for someone to come and check out the damage and the next day they came in inspected the damage and gave me a great quote which was the best deal around the county.

Glad we were able to help you. Thank you
I could not be happier with the entire process! Very professional and informative right up front. Their pricing is great and the work is even better. Thanks and I look forward to having the solar panels installed as well.
Thanks Mike, always good to help good people.
The whole process was easy and affordable. Jim explained everything perfectly and the crew was very professional. Would definitely recommend Gen Sun, they were awesome!
Thanks for your kind words. We love helping Waldwick homeowners and please say hi to your mom, as well.
Roof replacement is not a "glamorous" project, so it can be nerve-wracking. From initial contact, to the bid, schedule and job completion, everything was easy and flawless! I appreciated all of the instructional videos, the finance options, the great price, the project updates - every step of the way. The crew was attentive with clean up too. Thank you!! I would highly recommend GenSun!
Thank you so much for your kind words, its always refreshing to work with diligent homeowners who actually take the time to properly evaluate Roofing companies the proper way, as you have.
It was a very experience working the GenSun. Very good free estimate with detail video. Work was done as promised. I worked with Coach Jim and he was always available when I need to talked to him. I will recommend GenSun to my friends for Roof replacement and Gutters.
Thank you and we look forward to helping you with the upcoming outdoor project.
The fact that they did an excellent job with the roofing and gutters on time, well done and fast was a great experience, the price is unbeatable, The Crews are awesome from the owner to the office.
Thank you Carlos. Very nice working with you and your wife and we look forward to doing your Siding project.
From the start to end, GenSun was fantastic. With all of the horror stories about contractors, I was a bit worried. This company showed up and went over and above to make sure we were satisfied. I highly recommend them.
Thank you so much
After much consideration and research, I decided to go with GenSun. Jim and Tom (project manager) were outstanding, explaining the whole process from beginning to end, and also accommodating my color choice when it seemed like it may have been difficult to fulfill. I was away traveling while the crew came and did the work, but from what I can see (and my neighbors who are nosy reported back), everything was done professionally, with respect to my house and the neighborhood. Coming home to see the finished product, I am truly blown away. The transformation for the house, as well as the quality of the workmanship is top notch, bar none. I would NOT hesitate at all to recommend the GenSun team to anyone looking to have roofing or gutters done. Going into the process I was a typical skeptical consumer, but after seeing how the team treated me and my house, I give a super big thumbs up recommendation without hesitation. Thanks again Jim for guidance through the whole process and explaining everything, as well as having a team of professionals do the install.
Thank you so much Joe! The gutters are being installed today, as well
GenSun Roofing gave me a very reasonable estimate for my job. Jim walked me through the process and the finished job was excellent. Their cleanup was immaculate. I’m totally satisfied with the total job. They also needed to remove and reinstall my solar panels, they also gave me the best estimate for this part of the job.
Yes, our pricing is kept low in relation to the quality of material and labor we bring to the table. so glad you recognized that!
The roof was done very quickly and looks good, but on the other side they left nails all over and did not reconnect the siding on side of house buy small roof other then that the roof is done .
Very happy with the new roof, jim is a nice guy with old school values, if you are looking to get a new roof look no further....
Thanks Frank and hope you were happy with the Gutter Guard job, as well.
Gensun Roofing was very professional from the manager and the workers. They were on time and clean up was good . I would recommend Gensun to my friends and family. Thank All of you Guys for a great job.
Thankyou for your kind words. We will be out to complete the gutter job next week, as well.
After receiving quotes from a few roofing companies we decided to go with Gensun Roofing to replace our roof as they use high quality material and their price was very reasonable. Jim kept us informed during the entire process. The crew showed up on time and finished the installation of the new roof the same day and even returning the next day to make sure everything was fine. We are very pleased with the job and would highly recommend this Company.
Thanks Jose and it was a pleasure working with you.
Honestly! I would definitely love to with you guys again. It was a great experience because I thought that dealing with the roof would of been a lot more stressful. But your company made it easy and stress free. Also did a job well done. Clean & professional
Thanks James! We look forward to your siding and window project.
